This work is directed to acquire better understanding and portrayal of the dissemination holding of comparable and disparate metals. It additionally meant to get ideal parameters for dispersion holding of aluminum covering over magnesium compound with Aluminum composite. This work targets building up a basic strategy to get dispersion holding joints at moderately not ease. On one hand, the exploration is expected to set up a strategy. This technique is concocted to contemplate the physical wonders that have huge effect on dissemination holding, for example, time, temperature, weight on joints and metallurgical qualities. Elastic and shear tests are to be directed. This work is directed to acquire better understanding and portrayal of the dispersion holding of comparable and unique metals. It likewise intended to ge t ideal parameters for dissemination holding of aluminum covering over magnesium combination with aluminum composite. These two metals are jointed inside the kick the bucket in the wake of completing surface treatment. At that point the bite the dust is kept inside the dispersion holding machine by shifting the time, temperature, weight by methods for burden.

This article concerns the tribological properties of three selected polymer materials: polyamide PA6, polyethylene PE-HD and polyetheretherketone composite PEEK/BG during sliding against aluminium alloy EN AW-2017A in the presence of hydraulic oil HLP 68. The tests were carried out under contact pressure p of 3.5–11 MPa at ambient temperature T ranging from −20 °C to +20 °C. The dependence of kinetic friction coefficient μk on the two parameters was determined through tribological tests carried out using a pin-on-disc tribometer. A five-level central composite rotatable design (CCRD) was adopted for the experiment. All the test results were statistically analysed. The microhardness of the surface of the polymeric material was measured before and after the friction process. The surface was also examined under SEM. Temperature and contact pressure have been found to have a significant effect on the tribological properties of the tested sliding pairs. Relative to the applied friction conditions, the surfaces after friction showed rather heavy signs of wear.
